  1. AUTOMATIC RAILWAY GATE CONTROL SYSTEM

  2. Railroad Crossing Through Ages: Previously, no gate or barrier was used at rail crossings. After some period, flagmen were posted to rail crossings to warn the traffic about the incoming train. Generally they used flag or lamp to do their job. Later manually controlled barricades were introduced. The gates were intended to be a complete barrier against intrusion of any road traffic on the railway.

  3. Disadvantages Of Manual Rail Crossing: Manual rail crossings need a lot of man power to do the job of signaling and operating the barrier. So manual rail crossing is not cost efficient. Most of the time this procedure is not time efficient. Often train arrives a long time after the gate has been closed. Manual system is erroneous, and can cause severe damage which may worth a heavy loss of life and capital.

  4. Automatic rail crossing: To avoid human error and to enhance efficiency, railway crossing system can be controlled in an automated manner. In an automatic rail crossing system a train which approaches the gate is detected by a sensor, and also the speed of the train is noted. Then the time taken by the train to reach the road is calculated and the gate/barrier is closed down accordingly. Also the departure of the train is detected by another sensor and the gate/barrier is restored to its initial position.

  5. Now we are going to present our automatic rail crossing system

  6. Equipments: • Microcontroller Unit ATMEGA16 • LEDs AND Light Dependent Resistors(LDR) • LM324 OPAMP • DC Stepper Motor (5 wire unipolar type) • ULN2003A (motor driver) • Resistances for proper biasing, control and safety measure • An LCD Display

  8. Algorithm: Micro controller Barrier Closed Train Sensed Micro controller Barrier Opened Departure Sensed

  9. FEATURES OF THE SYSTEM: Automatic Train Sensing Traffic Signal Control Warning Buzzer Obstacle Detection Gate Malfunction Detection Auto Communication With Train

  10. BLOCK DIAGRAM

  11. METHOD OF TRAIN DETECTION : Train detected by LDR Train approaching sensor

  12. Gate Control: No Train Green Signal On

  13. Gate Control: Train Detected Yellow Signal On

  14. Gate Control: Train Approached Red Signal On

  15. Signals Sent to The Train: When there is no crossing ahead. When the train is approaching a rail gate When train crosses a rail gate

  16. Signals Sent to The Train: If an obstacle is detected on the line after the gate is closed In case of a gate failure

  17. Limitations • Light Sensors were used. • No wireless communication with train is done in this project.

  18. Future Improvements • Backup motor system can be added. • Automatic train deceleration. • Effective wireless communication.
